Cold weather mold

Most Penicillium species grow well over lower temperature ranges, with nearly all capable of growth below 5 C/41 F. Its growth at low temperature has led to Penicillium being referred to as the cold weather mold. ... 

Zffimid . QDuPont] Toughened HDME resin, rdnfixced for inj. and blow molding, sheet, structural foam, ther-moftwming, lawn and garden equ., industrial machinery, cold weather supplies. 

Resin lamination should not be carried out at a temperature of less than 20C (68F). A catalyzed/promoted resin is heat-sensitive and catalyst levels should be adjusted to varying temperature as recommended by the manufacturer. With resin laminating, where space is limited, mold preparation such as releasing and gelcoating can be done in a tent made of polyethylene film (which can also be used as a warm area for curing resins in cold weather). 

This is another version of cold forming by utilizing a thermoformed plastic skin to impart an excellent surface and other characteristics (for weather resistance, etc.) to a cold-molded RP. For example, a TP sheet is placed in a matched mold cavity with an RP uncured material placed against the sheet. The mold is closed and the fast, room temperature curing plastic system hardens. The finished product has a smooth TP-formed sheet backed-up with RP. 

Comoforming n. A fabrication process that combines vacuum-formed thermoplastic shapes with cold-molded fiberglass-reinforced resin to produce parts having excellent surface appearance and weatherability. 

Silicone, which is the representative industrial product of organosilicon compounds, has many characteristic properties such as heat resistance, weather resistance, cold resistance, electric insulating, water repellency, antifoaming properties, mold release properties, lubricating properties, etc. Hence the silicones are used in various industrial fields [31].
