Hapcoat™ 3720

A two-component, room temperature curing, medium to high thixotropic, readily machinable, surface coat developed especially for use with plaster as a backup plastic.

Being thixotropic, HAPCOAT 3720 is ideally suited for use on vertical or sloping surfaces where flow or drain-off cannot be tolerated.

• Easy to sand and work, and should be used on those pattern-making applications where additional machining is required.

• Plastic surface for plaster castings.

• Inexpensive, fast castings, used for molds, metals, or patterns

Advantages:

• May be applied & wet plaster poured as a backup in a wet state. The two systems will bond, forming a plastic faced/plaster backed system.

• This surface coat has no abrasive filler in it, and is easily worked by all wood cutting tools

• The white color of this face coat is ideally suited for scribing with marking inks to outline pattern changes, etc.

• Reproduces the finest surface detail and texture
