This technique is casting a pre-prepared compound (a mixture of binder, filler, auxiliary, and modifying additives) into a mould. Depending on the type of resin, gelcoat, and filler, the artificial stone can imitate natural marble, malachite, jasper,
translucent onyx or granite.
The products made using this technology have excellent surface quality and chemical, abrasion and thermal resistance. They are quite affordable for customers.
Examples of application:
1. tabletops and window sills 2. baths and jacuzzis 3. sinks 4. finishing panels

Basic materials:
NORSODYNE
H13
Orthophthalic pre-accelerated casting resin to make kitchen sinks. Gel formation time 14-18 minutes.
NORSODYNE
C55
Neopentyl glycol-based isophthalic resin for hard surfaces. With UV stabiliser. Fills well. Gel formation time 10-12 minutes.
POLYCOR
NPG
SANITARY
Neopentyl glycol-based white isophthalic gelcoat. To make sinks and baths.
POLYCOR
ISO NPG
CLEAR
Neopentyl glycol-based transparent isophthalic gelcoat. For spraying. To make kitchen sinks.
FASTCOTE
LP
Semi-permanent release agent to extract polyester or vinyl-ester based fiberglass products from open moulds. The compound is easily applied and leaves a deep gloss without polishing.
MARBOCOTE
625X
Release agent made of wax and polymer resin. Makes a good gloss. Can also be used as an ordinary wax, though the number of times of usage is much higher.
LITHOPOL
Polyester granule (chips) to fill resin or gelcoat. Imitate the stone structure.
Advantages of the technique:
1. wide range of models, vast choice of colours and combinations 2. technology can be adjusted for small- and large-scale production 3. high productivity and low cost
Disadvantages of the technique:
1. limited choice of shapes 2. competition with traditional materials
