Chavant NSP clay is a globally well-accepted non sulfur modeling clay used by the Special Effects and Fine Arts industries.
It holds exceptional surface details and is somewhat waxier and tougher than other Chavant products.
Available in: Soft, Medium, and Hard
Colors: Green, or Brown
PACKAGING:
2 lb block (.907 kg.)
10 lb block (4.53 kg.)
NSP was introduced in 1993. The intention was to eliminate the sulfur filler in a professional grade sculpting clay, which often
caused inhibition problems with various liquid rubber mold-making materials.
The NSP product line consists of clays that contain higher percentage of wax components making the clays somewhat “tougher”. Available
in Soft, Medium or Hard, these clays have good adhesive qualities, flexibility and length. Because they are “tougher” NSP tends to accept
cut detail lines very cleanly, with no ragged edges. The surface texture of NSP will be somewhat “grabby” when compared to sulfur-based
clays and even the NSP – Soft is rather firm by some people's standards.
NSP is commonly used by artists for the creation of sculpture and is often used to fill cracks in industrial patterns or to build dams
when making splash molds. Product designers who freehand sculpt also use NSP.
NSP is subject to surface oxidation. If the clay is in its original package it will have a long shelf life. If the clay is repeatedly heated and cooled, oxidation is accelerated. Sometimes this characteristic is beneficial in handling or
mold making since the surface can become harder.

Handling Tips
NSP™ clay scrapers and rake tools are often used to initially make the clay surface uniform. NSP™ is very solvent friendly; solvents such as naphtha, clear mineral spirits and turpentine
are aggressive solvents which can be used to quickly soften and dissolve the surface. Citrus based solvents such as D-limonene can also be used but may cause inhibition when molding the
clay using silicone rubber. 99% Isopropyl alcohol can be used to smooth the clay surface if a less aggressive solvent effect is desired.
NOTE: If isopropyl myristate is used on the surface of NSP™, the surface will remain soft, and it will not return to the
original hardness.
