The invention is a method for manufacturing a surface covering product having a gloss controlled surface wearlayer coating and a curable composition used in that method. The preferred curable composition is a polymerizable coating which includes a di-isocyanate and/or isocyanurate structure, a polyester polyol, a hydroxy and acrylyl functional polyester, mono, di, or tri-functional acrylates, and a flatting agent and/or hard particulates. The preferred surface covering product is a floor covering product produced as a vinyl film that is precoated with preferably a wearlayer coating that is adhered to the vinyl film, and the surface of the film is preferably embossed. A gloss controlled surface coating is achieved by application of the preferred composition to the printed sheet of film, and the composition is then exposed to low intensity ultraviolet light followed by exposure to ionizing radiation from a low accelerating energy electron beam, which forms an abrasion resistant wearlayer with non-visible degradation of the printed film.

A lumber kiln is controlled by a digital computer which periodically changes the wet bulb set point so that the rate of change of moisture content is maintained approximately constant. Reversible fans which circulate air through the lumber are periodically reversed. When they are reversed, the signals from the temperature sensors are reversed so that the temperature from the sensor at the high pressure end of the circulating air path is always used. A plurality of kilns may be controlled by the same digital computer because the computer is insensitive to variations in the operating parameters of the kilns.

Kiln control system

An improvement in devices for determining the moisture content of lumber by measuring the electrical resistance of the wood. A biasing system is provided so that the voltage supplied to the electrical contacts disposed in the wood may be adjusted. This arrangement allows for corrections to be made in the electrical operation of the device, which corrections compensate for anomalous properties of the wood.

Polyvinyl chloride injection-molding compounds resistant to splitting when nailed during assembly operations comprising a polyvinyl chloride-based resin, from 15 to 25 parts per 100 of the base resin of chlorinated polyethylene, from 20 to 80 parts per 100 of styrene-acrylonitrile copolymer and from 5 to 15 parts per 100 of a styrene-butadiene random or block copolymer rubber.

Nailable vinyl chloride-based injection-molding compound

A method for making a composite mold utilizing room temperature vulcanizing silicone rubber for the surface of the mold and room temperature vulcanizing polyurethane rubber for the rest of the mold.
