LIQUID POLYURETHANE RUBBER
MC-PU80
Description of 1:1 80 Shore A liquid polyurethane rubber for sole molds
Polyurethane rubber consists of A&B component, which, after mixing, cure at room temperature to flexible, high-strength, mold rubber. It can make durable molds for casting plasters and waxes, cement.
Characteristics of 1:1 80 Shore A liquid polyurethane rubber for sole molds
It 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.

Applications of 1:1 80 Shore A liquid polyurethane rubber for sole molds
Suitable for making the mould of cultural stone, concrete stamping mats. It also applies to electrical equipment potting, rubber rollers, Ski and snowboard ,rubber plates, rubber wheels, and others.
Using Instructions of 1:1 80 Shore A liquid polyurethane rubber for sole molds
NOTE: To ensure thorough coverage, lightly brush the release agent with a soft brush over all surfaces of the model. Follow with a light mist coating and let the release agent dry for 30 minutes. Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.
Measuring & Mixing...
Liquid urethanes are moisture sensitive and will absorb atmospheric moisture. Mixing tools and containers should be clean and made of metal or plastic. Materials should be stored and used in a warm environment (73°F/23°C).
IMPORTANT: Stir Part B thoroughly before dispensing. After dispensing equal amounts of Parts A and B into mixing container, mix thoroughly for at least 3 minutes making sure that you scrape the sides and bottom of the mixing container several times.
If Mixing Large Quantities (16 lbs./7 kgs. or more) at one time, use a mechanical mixer (i.e. Squirrel Mixer or equal) 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.
Although this product is formulated to minimize air bubbles in your the cured rubber, vacuum degassing prior to pouring rubber will further reduce entrapped air.
Pouring, Curing & Performance...
For best results, pour your mixture in a single spot at the lowest point of the containment field. Let the rubber seek its level up and over the model. A uniform flow will help minimize entrapped air. The liquid rubber should level off at least 1/2” (1.3 cm) over the highest point of the model surface.
Curing - Allow rubber to cure a minimum of 16-24 hours at room temperature (73°F/23°C) before demolding.
Using The Mold - If using as a mold material, a release agent should be applied to the mold before each casting.
Performance & Storage - Fully cured rubber is tough, durable and will perform if properly used and stored. The physical life of the rubber depends on how you use it.
Package of 1:1 80 Shore A liquid polyurethane rubber for sole molds
20Kg/drum or 200Kg/drum.
Shelf life of 1:1 80 Shore A liquid polyurethane rubber for sole molds
For best results, store products in unopened containers at room temperature (60-90°F/15-32°C). Use products within six months.
