-Polyurethane rubber silicone rubber

-Latex plastic adhesive (hot melt)

These systems can be used to produce various precast concrete products and have options for castability, brushing, and spraying.

Casting stone using PU mold rubber, liquid polyurethane or silicone rubber molding rubber. These mold rubbers can excellently replicate surface details, provide excellent dimensional stability, have an unparalleled service life, and have higher durability compared to hot melt and polypropylene systems. Polyurethane molds can be completed in a shorter time (about 16 hours demolding time) compared to latex rubber molds. If properly maintained, these molds will last for several years and produce thousands of stones.

Decorative surface material

Pour Polytek liquid rubber onto textured patterns (such as slate, bricks, pebbles, slate, etc.) to create reusable embossing tools and texture the surface to impart the desired texture to concrete floors, walls, or other surfaces. Concrete stamping is used to manufacture artificial stone walls, textured pool decks, sidewalks, terraces, lanes, stairs, countertops, etc

countertop

You can create the entire shape and texture of the countertop, or combine it with rigid forms to create individual countertop elements. These include sink inserts, decorative edge and decorative strips, drainage boards, etc

Background decoration

Stones, rock wall lining, fire pits, retaining wall blocks, pier wall covers, etc

Concrete: Hard coating

Polytek ® Polyurethane plastics can be used for hard coatings on hard surfaces, such as EPS foam, low-density machinable wood substitutes, MDF or wood. These two-component room temperature curing systems have two options: washable and sprayable. One or more layers of coating can be applied to create finished models or prefabricated forms for concrete casting. Cured plastics are easy to polish or machine.



EasyFlo Spray FR liquid plastic (gel time 5s, curing hardness D72)

The fast curing sprayable polyurethane system is used to hard coat hard surfaces (such as cut EPS foam, MDF or wood or low-density machinable wood substitutes). This thin, tough, and easy to polish coating can be applied in one or more layers. This is a flame-retardant product: UL-94 (V-0).



EasyFlo series liquid plastics and PolyFiber II

The plastic can be sprayed with a PlakPak spray gun.



For fast curing brush coated hard coatings, PolyFiber II thickener is added to EasyFlo series liquid plastics to give these low viscosity resins a brush coating thickness. Use EasyFlo 60 or EasyFlo 95 (slower version of gel) plastic.

Copying architectural patterns (vertical surface operation - painting or spraying)

polygel  ® Series - After mixing these rubbers, they are easy to apply or spray, and are used to make thin layers of soft rubber for molds. The mixing ratio is 1:1, easy to operate, and the color can be adjusted according to needs. Good dimensional stability.

The layer thickness can be stacked. When making the next layer, ensure that the front thin layer has enough gel (usually about 1 hour). The ideal mold thin layer thickness is 1/8 to 3/8 inch.

Auxiliary application materials

Pol-Ease ®  Mold Dressing PU Rubber Mold Protective Agent

A thin liquid that can protect molds exposed to solvents or petroleum based release agents and/or harsh casting materials (such as porous and absorbent materials).

Pol-Ease ®  Mold Rinse is a concentrated solution that can reduce Polytek ® Surface bubbles on gypsum castings made from rubber molds. The mold should be immersed or sprayed with a portion of Pol Enzyme diluted with 10 parts of water ® Mold rinsing solution. When pouring plaster, the mold should be wetted.



PolyPurge Dry Aerosol Gas Aerosol

Before resealing the rubber component, spray PolyPurge into open polyurethane containers A and B to replace humid air and extend product life.



Pol-Ease ®  2601 Release Agent: A water-based and environmentally friendly release agent used for concrete or gypsum molded products, effectively extending the life of the mold.

DH-9719 release agent: paste release wax used for casting polyurethane rubber molds
