Polyplex 225 molds casting

Polyplex 225 molds casting

For the production of flexible molds in casting.

100% solids 100% elongation for making molds by casting

Production of flexible casting molds Polyplex 225 – for the production of flexible casting molds – a thick liquid made of two-component hydrophobic elastomeric polyurethane, flexible and hard, wear-resistant, 100% solids, which polymerizes from a reaction between the base and the hardener. Unlimited thickness and powerful, for making molds for cold casting models. Plaster, epoxy, concrete, acrylic solutions, etc. can be poured into the mold.

POLYFLEX FORMING 225 100% SOLIDS, TWO COMPONENT  FLEXIBLE FOR INDUSTRIAL STRONG FORMING

  For the production of extremely flexible and strong molds for casting, resistant to wear with a unique molecular structure, resistant to wear and mechanical blows and suitable for regular multiple use.

Characteristics:

• Flexible extends at  least 100%  .
• A perfect seal from water, repels moisture and prevents penetration.
• Resistant to mechanical blows.
• Abrasion resistant.
• Can be applied in one casting without thickness limitation.
• Resistant to thinners and chemicals.
• Excellent adhesion to the infrastructure.
• Easy to apply and dries quickly.
• Rests for casting and levels well.
• 100% solids  without diluents and without smell .
• Flexible and absorbs shocks and hard and violent mechanical blows and is suitable for making molds.
• If pouring materials such as leveling epoxy, coat the mold with silicone 350 in a thin layer to prevent sticking and easy separation.

uses:

• for the production of flexible molds
