FormLastic 48 /7,9kg

Formlastic™ 48 urethaan is een duurzaam vormrubber gemaakt voor productiegieten van beton. Het heeft een lage viscositeit voor gemakkelijk mengen en gieten en hardt uit met minimale insluiting van bellen. De mengverhouding is 1A:1B op volumebasis, de verwerkingstijd is 25 minuten en het rubber hardt uit met een ultieme Shore-hardheid van Shore 48A. Uitgehard rubber is maatvast (lage krimp), biedt een goede slijtvastheid en geeft kleurnauwkeurige betonafgietsels.

BELANGRIJK: Dit product bevat geen kristallijn silica.

Instructions

START BY PREPARING YOUR MODEL...

Preparation - Store and use at room temperature 23°C. These products have a limited shelf life and should be used as soon as possible. Environmental humidity should be as low as possible. Good ventilation (room size) is essential. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.

Some Materials Must Be Sealed - Models with porous surfaces (gypsum plasters, concrete, wood, stone, etc.) must be sealed prior to applying a release agent. Sonite™ Wax available fromForm X is a proven sealer for porous surfaces.

Non-Porous Surfaces - Metal, glass, hard plastics, sulfur free clays, etc. require only a release agent.

Applying A Release Agent - Use a release agent made specifically for mold making Universal Mold Release™ available fromForm X. A liberal coat of release agent should be applied onto all surfaces that will contact the rubber.

IMPORTANT: To ensure thorough coverage, lightly brush the release agent with a soft brush over all surfaces of the model. Follow with a light mist coating and let the release agent dry for 30 minutes.

Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.

MEASURING & MIXING...

Liquid urethanes are moisture sensitive and will absorb atmospheric moisture. Mixing tools and containers should be clean and made of metal or plastic. Materials should be stored and used in a warm environment 23°C

Important; Pre-Mix Part B Before Using. Using a flat edge paddle or a drill mixer, scrape sides and bottom of container several times.

POURING...

For best results, pour your mixture in a single spot at the lowest point of the containment field. Let the rubber seek its level up and over the model. A uniform flow will help minimize entrapped air. The liquid rubber should level off at least 1.3 cm over the highest point of the model surface.

CURING & PERFORMANCE...

Curing - Allow rubber to cure a minimum of 24 hours at room temperature 23°C before using. Cure time can be reduced with mild heat or by adding Smooth-On “Kick-It ™” Cure Accelerator. Do not cure rubber where temperature is less than 18°C.

Post Curing - Optional . . . Following a 24 hour cure, heating the rubber to 65°C for 4 to 8 hours will increase physical properties and performance.

Using The Mold - A release agent should be applied to the mold before each casting. Aquacon™Water Based Release Agent available from Form X is recommended for releasing abrasive materials like concrete.
Performance & Storage - Fully cured rubber is tough, durable and will perform if properly used and stored. Molds should be stored on a level surface at room temperature in a dry environment. Do not stack molds, expose them to moisture or UV light for prolonged periods.
