Product Description
Good Price 50 Shore A Two Parts Moulding Liquid Polyurethane Rubber
Product Description 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: 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. Application: Substitute for Silicon rubber to make the mould of "cultural stone". Liquid polyurethane rubber also applies to electrical equipment potting, rubber rollers, Ski and snowboard ,rubber plates, rubber wheels, shoe models and others.

USING INSTRUCTION 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).
Notes: 1.Always wear a respirator or self -contained breathing apparatus when working with urethanes. 2.Use between 65F and 75F in a humidity-controlled environment. 3.Liquid polyurethane rubber is always best to mix the material by hand, with a plastic or metal mixing utensil.Avoid mixing with drill motors because of the friction they generate, mixing with electric drills can start the exothermic cure process and cause the product to cure in the mixing container. 4.Don't vary the mix ratio. Unlike some polyester resins, altering the mix ratio to vary the cure cycle will not work with urethanes. 5.Mix in clean plastic containers. Paper cups and wooden mixing utensils may contain moisture which can adversely affect the urethane rubber. Avoid waxed paper cups because the wax may melt and contaminate the rubber. 6.Air bubbles in urethanes are almost always caused by moisture. Do everything possible to avoid moisture getting into the mix. 7.Replace the lids onto the containers promptly after use. Do not use the urethane rubber during rainy days or times of high humidity. 8.Avoid pouring against an unsealed water based product such as plaster or hydrocal. Seal plaster or hydrocal with a product like Krylon Clear Acrylic. 9.Avoid mixing a large batch- The larger the batch, the more exotherm or heat is generated in the cure cycle. If you are making a large mold, mix small batches to make the process more manageable. Storage:Store Liquid polyurethane rubber 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 6 months. 1.Re-cap the bottles immediately after use. 2.Extend-It aerosol nitrogen blanket can be used to protect the product from moisture contamination. Package:20Kg/drum;200kg/drum
