Polycraft SG2000 Polyurethane Casting Resin 500g Casting & Modelling

Please note that this resin sets quickly, 2 - 3 minutes. Have everything prepared before mixing.

SG2000 - Polyurethane Resin System

This versatile Polyurethane Resin System, known as SG2000, finds applications in various fields such as creating patterns, negatives, castings, models, vacuum-forming tools, and prototypes, among others.

Mix Ratio: It's important to maintain a 1A to 1B ratio by weight.

Pot Life at 200g/20°C: You'll have a working time of 2.5 - 3.5 minutes.

Demould Time: Your creations will be ready to be demoulded in just 30 - 60 minutes.

Shore D Hardness: Achieve a hardness of 72±2.

Heat Resistance (HDT) DIN EN ISO 75 B (Celsius): This resin system exhibits a heat resistance of 86±3 degrees Celsius.

Viscosity at 25°C (Mixed): The mixed resin has a viscosity of 50±5.

Cured Colour: After curing, you can expect a white or off-white finish.

Each kit contains containers with the same weight, but it's worth noting that part A contains a filler powder additive, which increases its volume. Therefore, to ensure accurate mixing, it's essential to measure equal weights of both part A and part B. Remember to shake well before use.

Before you start, ensure that both Parts A and B are at room temperature and that your tools, moulds, or models are ready for action. The surfaces and air temperature must be above 16°C during application and throughout the entire curing process. Use metal or plastic mixing vessels and spatulas to prevent moisture introduction, avoiding paper or wood tools. Measure equal weights of part A and part B into a mixing container, like a polyethene pail, and mix thoroughly for one minute, making sure to scrape the sides and bottom. Pour the mixture into your mould cavity.

Once you open the containers of Parts A and B, make sure to either use them or seal them tightly, as exposure to atmospheric moisture can lead to unwanted foaming of the plastic.
