Low Hardness Low Density Master Models Tooling Paste Epoxy Resin Materials
Brown Color Low hardness Low Density Epoxy Resin Tooling Paste For Mould Shaped Fine Surface Structure
Product main properties
This product is a two-component materials, by automatically output device fast coating model, single coating thickness can be up to 40 mm, reaction put the quantity of heat low, coating and processing when no smell, room temperature curing can be carried out after a day of machining, machining performance is good, good surface effect, material size stability is good
Characteristics:
easily shaped and machined,fine surface structure
Applications:
yacht model,benchmark model, system and sand-cast model, rapid prototype,etc.
Product operation process
Given according to the proportion of fully mixing thoroughly, the same color. Try to avoid to produce bubbles, it is best to use vacuum mixer mixing. Strict control, with a thick layer of a coating is not more than 40 mm;If upset, after waiting for curing the second floor. The after curing processing, performance is better. (after curing: 80 ℃ + 8 h or 3 days) at room temperature, curing can be after rough machining, precision work after 3 days;The material of metal, composite structure materials such as sticky relay is extremely strong, mold release agents shall be used for rolling over. Make sure the strength of the support frame, stability and cleanness, machine
