Polyurethane Mold Rubber for Precast Concrete/ Cast Stone Mold Making

Description

Description:

Polyurethane Mold Rubber are great for precast concrete / cast stone mold making, manufactured stone mold making, and concrete casting.  It consists of two parts(A&B), which after mixing, cure at room temperature to flexible, high-strength, mold rubbers.

Why Polyurethane Mold Rubber is Great To Make Precast Concrete/ Cast Stone Mold Making?

Precast Cast stone is a highly refined building material, a form of precast concrete used as masonry intended to simulate natural-cut stone. It is used for architectural features: trim, or ornament; facing buildings or other structures; statuary; and garden ornaments. So normally it needs to print different kinds of pattern designs. The price you pay for cast stone depends on several factors, such as size, design, ornamentation, and desired color.

Costs are much lower if one side of the mold design is flat. Such profiles include water tables, banding, headers, coping, sills, and bases. The cost of cast stone increases if one side of the mold is designed in an L-shape or U-shape. This is because more complex pieces require a more intricate mold and additional time for production. Costs become even higher for stone pieces requiring two-sided molds.

So choosing a high-performance cost mold material is quite important, please check the features of polyurethane mold rubber, which will help you find the answer:

Features:

What are the advantages of polyurethane mold rubber to make your precast /cast stone molding?

1.) Reusable ~ Molds can be used over and over again.

2.) Does not shrink ~ Has good abrasion resistance.

3.) It comes in a wide range of hardnesses, giving long mold life.

4.) It can be poured, brushed, or sprayed onto the original model.

5.) It is the most economical overall (compared to other mold rubbers).

Data Sheet:                            

Operation Method:

Both pouring and spraying are available, while if you want to brush, we have a thickening agent to adjust the viscosity of polyurethane mold rubber for brushing.

Storage:

Store in a cool and dry place. If you can’t use one drum up at a time,  please inject N2. The storage time of the original packing is 6 months.

Warm Tips:

To ensure dimensional accuracy and maximum life period, moulds made of JH polyurethane mold rubber are preferably stored in their supporting mould under air admittance. Prolonged compression may lead to irreversible deformation. The moulds must be protected against UV irradiation and direct insolation.
