Detailed Product Description

Product Description

Molds Making Liquid Polyurethane Rubber


Description of Urethane Liquid Rubber For Mold Making :
Liquid polyurethane rubber consists of A&B component, B is curing agent, and A is polyurethane prepolymer. It can also be used as a concrete or cement stamping mold as well as for making hard durable rubber parts for machinery or automotive applications.

Characteristics of Urethane Liquid Rubber For Mold Making :
Liquid polyurethane rubber has excellent processing properties, solid in common temperature, shorter gel time, and regulating color by adding pigment. The ware has good properties of abrasive resistance, hydrolysis resistance, transparent, good resilience, stable dimension.

Applicationof Urethane Liquid Rubber For Mold Making :
Substitute for Silicon rubber to make the mould of "cultural stone". It also applies to electrical equipment potting, rubber rollers, Ski and snowboard ,rubber plates, rubber wheels, shoe models and others.

USE INSTRUCTIONS
1.Liquid urethanes are moisture sensitive and will absorb atmospheric moisture. Mixing tools and containers should be clean and made of metal or plastic.

2. Stir Part B thoroughly before dispensing. After dispensing equal amounts of Parts A and B into mixing container, mix thoroughly for about 3 minutes making sure that you scrape the sides and bottom of the mixing container several times.

If mixing large quantities at one time, use a mechanical mixer for 3 minutes followed by careful hand mixing for one minute as directed above. Then, pour entire quantity into a new, clean mixing container and do it all over again.

3. Vacuum de-airing equipment is recommened if available.Vacuum degassing prior to pouring mixture will further reduce entrapped air.

4. For best results, pour your mixture in a single spot at the lowest point of the containment field.

5. A small-scale test is recommended before mass production.

6. For better performance, allow the mixture dry for 24 hours before demolding. It can also be heated for post curing.

7.Release agent should be applied to the mold before each casting.

8.Materials should be stored and used in a warm environment (73°F/23°C).

 

PACKAGE AND STORAGE:
Store in cool and dry place. If you can't use one drum up at a time, please inject N2.The storage time of original packing is 6months.
1.Re-cap the bottles immediately after use.
2.Extend-It aerosol nitrogen blanket can be used to protect the product from moisture contamination.
Packing:20Kg/drum or 200Kg/drum.
