Liquid polyurethane rubber product description
Liquid polyurethane rubber is composed of components A & B, B is a vulcanizing agent, and A is a polyurethane prepolymer. It can also be used as concrete or cement stamping dies, and to make hard and durable rubber parts for mechanical or automotive applications.
Characteristics of liquid polyurethane rubber:
It has excellent processing performance, is solid at room temperature, and has a short gelation time. The color can be adjusted by adding pigments. The product has good wear resistance, hydrolysis resistance, transparency, good resilience and stable size.
Application of liquid polyurethane rubber:
Instead of silicone rubber to make "cultural stone" molds. It is also suitable for electrical equipment potting, rubber rollers, skis, snowboards, rubber sheets, rubber wheels, shoe molds, etc.

Instructions:
mix:
1. Shake sides A and B vigorously. Shake or stir well before use Liquid ingredients may settle in container during storage. Let it sit for a few minutes to allow any air bubbles to rise to the surface after shaking the container.
2. Measure equal volumes of A and B into a clean plastic or metal container.
Combine both sides into a third clean mixing container and mix vigorously for at least one minute, taking care to scrape the sides and bottom of the mixing container with the mixing utensil, until the product is uniform in color.
noPrecautions:
1. Always wear a respirator or self-contained breathing apparatus when using polyurethane.
2. Use in a humidity controlled environment between 65F and 75F.
3. It is always best to mix materials by hand with a plastic or metal mixing utensil. Avoid mixing with motor drills as they create friction and mixing with an electric drill will start the exothermic curing process and cause the product to cure in the mixing container.
4. Do not change the mixing ratio. Changing the mix ratio to change the cure cycle does not work with polyurethanes, unlike some polyester resins.
5. Mix in a clean plastic container. Paper cups and wooden stirring utensils can contain moisture, which can adversely affect urethane rubber. Avoid waxed paper cups, as the wax may melt and stain the rubber.
6. Bubbles in polyurethane are almost always caused by moisture. Do everything possible to keep moisture out of the mixture.
7. Put the lid on the container immediately after use. Do not use urethane rubber in rainy weather or when there is high humidity.
8. Avoid pouring on unsealed water-based products such as plaster or hydrocal. Seal the plaster or hydrocal with a product such as Krylon Clear Acrylic.
9. Avoid mixing large batches – the larger the batch size, the more exotherm or heat will be generated during the cure cycle. If you're making large molds, mix up small batches to make the process more manageable.
Storage of liquid polyurethane rubber:
Store in a cool dry place. If you can't use up a bucket at a time, inject N2. The storage period in the original packaging is 6 months.
1. Recap the bottle immediately after use.
2.Extend-It aerosol nitrogen blanket can be used to protect products from moisture contamination.
