Polyester Polylite 33542 - 75 pitch matrix
POLYLITE 33542 - 75 the preaccelerated polyester pitch containing a filler intended for lamination of fiberglass forms (matrixes). This matrix pitch represents development of successful system for production of the Polylite Profile forms, keeping all properties of original pitch and adding advantages of use of the only product with standard catalysts.
Primary properties: low shrinkage - a form precisely reproduces model. In a ready form there is no residual tension. Usually additional hardening is not required. Change of color when hardening (the visual indicator of control is built in). High temperature of thermal deformation (HDT) - 115 * S. Vozmozhno for once to gain thickness to 8 mm.
IMPORTANT! Owing to existence in pitch of a special filler and high viscosity (4000 - 5000 mPa) and the high density (1,37 g/cm3), pitch has property to precipitate a dense bed even at small periods of storage. Having opened a bucket we will see from above a layer of dark liquid, and from below a viscous layer of pitch. Therefore before use it is necessary to mix carefully to homogeneous mass without lumps, yellowish - beige color for ensuring uniform distribution of a filler.
Density is 1,37 g/cm3. At addition of 1,25% of the PEROXIDE catalyst No. 1 at a temperature of 18 - 25C * time of jellification of 35 - 45 min.
It is delivered in buckets on 20 kg. Is on sale only the whole bucket of 20 kg. On demand we will provide the complete technical specification.
