    LOWERING SILICONE'S VISCOSITY

    It is possible to reduce the viscosity of our TECHNO SIL series (silicon based molding resins) with the addition of our TECHNO FLUID according to preset percentages without drastically altering the characteristics and specifications of the selected product.

    This modification allows for a more fluid and effective casting, as well as a faster degassing process.

    TECHNO CAST 8101

    When working with epoxy casting resins such as TECHNO CAST 8101 to produce thermoforming molds, it is important to open the container for part A and to mix the different additives throughout its mass using a drill and a mixer (jiffy mixer) in order to obtain a perfectly homogeneous part A.

    If you don't mix correctly or sufficiently, the system will lose effectiveness and the product may not polymerize since part A is too rich in resin.

    Thus, the part A container should be opened and the bottom and sides scraped properly in order to obtain a completely homogeneous part A.

    POLYMÈRES TECHNOLOGIES... Field experience is invaluable.

    COLD WEATHER RESIN EXPOSURE

    It is very important to keep resin containers far from outside doors during the winter months.

    If the containers are exposed to cold, the viscosity of contents will increase drastically, reactivity will decrease considerably, and the additives will have a tendency to harden at the bottom of the container, a phenomenon called "hard pack".

    Moreover, unmolding times will also be significantly increased.

    Therefore, containers should be stored on pallets in an environment at 22 degrees C

    METALS CLEANING PROCEDURES

    When you want to assemble two metal parts with our structural adhesives (TECHNO BOND 3054, 3056, 8003, 8050, 8011, 8104, 8105 and 8106, among others), it is vital to undertake surface preparation on the metal, through either sandblasting, or manually with grade #80 sandpaper, followed by acetone cleaning, to remove oxidation from the metal surface and to create a surface profile.

    Afterwards, it is essential to apply the adhesive quickly since oxidation starts as soon as your surface pre-treatment is completed, leading to a new layer of oxidation within 24 hours (a greasy coating that creates a barrier between metal and adhesive). 

    Thus, we suggest that you apply our adhesives as soon as you finish the pre-treatment of the metal surface in order to get optimal results.

    TECHNO RELEASE 110 & 113

    Before using our TECHNO RELEASE 110 and TECHNO RELEASE 113 release agents, it is essential to mix the agent well for a few minutes in order to mix the different components to ensure that they are completely homogeneous. 

    Since the specific densities of those different components can vary, it is possible that, after a certain amount of time, the product's important components settle at the bottom of the container.

    Therefore, vigorous mixing will let you apply TECHNO RELEASE 110 or 113 very effectively leading to a quick unmolding of your parts.

    SPECIFIC GRAVITY

    The specific density of a product is very important when comes the time to compare product costs.

    In order to compare the cost of a product to another's, it is imperative to know its specific density and to transform the weight (kg) to volume (litre).

    Thus, 25 kg of product A with a specific density of 1.25 gr/cubic cm has a volume of 20 litres.

    That same 25 kg of product B, which has a specific density of 1.50 gr/cubic cm, equals a volume of 16.666 litres.

    Therefore, for the same price, product A has a higher volume (20 litres) than product B (16.666 litres).

    Using the price of those two products, it will then be possible to compare their cost per litre.

    A price comparison should be by volume (litre) and not by weight (kg).

    SILICONE SPRAYING

    Silicon-based release agents, such as TECHNO RELEASE 110 and 113, used with spraying equipment, produce silicon vapours that can stay suspended in the air for several days in a work environment and contaminate parts heading to assembly or painting. 

    These vapors will slowly deposit on parts and will contaminate them.

    It is therefore strongly suggested to vaporise the release agents in a specially prepared room that cannot leak those vapors.

    An ounce of prevention is worth a pound of cure.

    VACUUM DEGASSING SILICONE

    Exposing a silicon mix from our TECHNO SIL series to a vacuum increases the reactivity of molecules and significantly reduces its pot life depending on exposure time.

    Therefore, take this into consideration when casting.

    Pigment
    REACTIVE PIGMENTS

    In a global quality approach, POLYMÈRES TECHNOLOGIES works only with reactive pigments, specifically pigments that are an integral part of the chemical reaction through covalent bonds.

    Whether epoxy, polyurethane, silicon, or acrylic pigments, they are a part of the chemical polymerization reaction and are an integral part of the molecular chain.

    No universal pigment is used by our company since they weaken the system and tend to decanter and to integrate poorly into resins.

    POLYMÈRES TECHNOLOGIES, where quality takes precedence.

    PART B POLYURETHANE SENSITIVITY

    The B part of a polyurethane (isocyanate) system is very sensitive to ambient moisture.

    We suggest adding nitrogen to the B part of our various polyurethane based systems, specifically our TECHNO CAST 3000, TECHNO CAST 3100, TECHNO CAST 3200 and TECHNO FLEX series using our TECHNO DRY 7477 vaporizer.

    Applying TECHNO DRY 7477 to the B part will create a protective barrier between the resin and the cover, eliminating moisture penetration that could contaminate the isocyanate and cause a blowing reaction (moisture molecules that attach to isocyanate molecules and react among themselves through a blowing effect).

    RESINS CONTAINERS STORAGE

    It is important to store your resin containers in a place where temperature is at 22 degrees Celsius with a relative humidity under 60%. Your work environment must also meet those conditions.

    When we discuss pot life and polymerization time, all tests have been administered in those conditions and any changes will modify the results from the technical sheet.

    If your containers are stored at a lower temperature, viscosity will increase, pot life will increase, as will demolding time and total polymerization time.

    At a higher temperature, the opposite will occur, which means reduced viscosity, reduction of pot life, faster handling time, and more.

    SILICONE RELEASE AGENTS

    If you are casting a two-part silicon mold and you want to avoid the two parts adhering to each other, you can use Vaseline and mineral oil, in a 1 part Vaseline to 4 parts mineral oil ratio, which will produce an excellent release agent for this type of application.

    However, you must only apply a thin coating since this release agent will become a contaminant if applied too thickly, causing the silicon resin to not polymerize. 

    We suggest validating your technique before moving to production.

    MASS DENSITY

    When casting a part or mold, their mass density will have a large impact on polymerization time.

    Indeed, the exothermic reaction produced by a two inch thick mass will be higher compared to one only 1/8th of an inch (0.125), which will effect greater reactivity of the molecular chain as well as faster polymerization. Since the exothermic reaction takes place in the centre of mass, this heat will remain in the casting and will therefore yield a shorter polymerization time.

    In a 1/8 of an inch (0.125) mass, the lesser exothermic reaction tends to leave the mass and therefore slows down the reactivity of the molecular chain, which causes the polymerization time to be much longer.

    THERMAL SHOCKS

    When you apply postcuring to a high temperature system, it is important to leave the molds or parts in the oven at the end of the cycle when the oven is stopped in order to avoid thermal shock that could lead to significant shrinkage, or to parts cracking.

    ADDITIVE DISPERSION

    It is essential to always mix the filling agents of parts A and/or B, depending on the system, in order to get maximum results.

    Not mixing those additives will lead to a resin too rich in reactive materials and skew the stoichiometry of the mix leading to a system that does not polymerize or that stays sticky.

    DEMOLD TIME

    In order to maximize the precision of your parts and molds, it is vital to unmold them when they are completely polymerized.

    If you want a quick turnout for your molds, you must therefore ensure that unmolded parts are set on a holding fixture in order to preserve their dimensional stability.

    PRECISE MIXING RATIO

    A precise ratio and a perfectly homogeneous A/B mix ensures that product characteristics and specifications are met.

    Any variation will modify the results for your molds and parts.

    POST-CURING PROCEDURES

    Did you know that postcuring a regular or high temperature resin increases the shrinkage of a part or mold?

    Indeed, the postcuring process allows molecules to get closer together through covalent bonds and thus intensifies the shrinkage of a thermosetting system.

    This should therefore be anticipated.
