APPLICATION

PU 362 A + B Two component, unfilled with ultra low viscosity to which dry fillers can be added. 4 10 kg 48 kg 15-20 Shore D 68 General casting  where high filling is required.
PU 363 A + B Two component, low odour polyurethane system which contains no hazardous solvents with a quick demould time, good flow properties, and excellent surface detail and finish. 140 sec –
160 sec
2 kg,

10 Kg or 
    40 Kg
80 Shore D

70-75
Prototypes, model making, negatives, figurines, pattern making.
PU 364 A + B Two component, low odour, polyurethane system which is designed for thin sections or casting to 20mm thick. The material has a very quick demould time and is designed to be used unfilled. 110 sec –
130 sec

30 – 40 Shore D
70 – 75
Prototypes, model making, figurines.
PU 365 A + B Very good model reproduction of the mould, fast cure, low exothermic reaction and low shrinkage. 4 – 5 10 Kg or
50 Kg
40 – 55 Shore D

69
Foundry patterns, copy models, negatives, fast reproduction models and prototypes.
PU 3651 A + B Ultra low viscosity, odourless, with very low shrinkage. 4 10 kg 30-60 Shore D 70-75 Prototypes, patterns, models, negatives, figurines.
PU 3652 A + B Ultra low viscosity, odourless, with very low shrinkage. 4 10 kg 20-40 Shore D 70-80 Prototypes, patterns, models, negatives, figurines.
PU 3660A + B Two component, U.V. stable, hand casting polyurethane system which is optically clear when cured. Ideal for rapid prototyping, embedding or any type of clear casting with or without a vacuum. 15 - 20 1.555 kg 250 Shore D

80

For optically  clear models
PU 3660 SA + SB This material is the same as PU3660 but for larger castings. PU366S has a much longer pot life and demould time reducing exotherm and shrinkage. 50 - 60   250 Shore D

80

For large optically  clear model.
PU 3663 A + B Water clear semi flexible system with good adhesion strength and UV stability 25-30 2 kg 70-100 Shore A    60 For potting and embedding of components. Simulates clear water.
PU 3664 A + B As 3663 but needs to be cured at 50°c. Offers optical clarity without the need for vacuum. 45-55 @ 50°c 2kg 80-110 Shore A    50 For potting and embedding of components. Simulates clear water.
PU 3666 A + B A self de gassing, UV stable system with optical clarity designed specifically for Badge Doming applications 8 - 12 TBA 80 - 180 Shore D

PU 3670 A + B odourless PU system with high level of dimensional stability 5 10 kg

50 kg

50-60 Shore D 75-80 Produces ultra fine detail and dimensional stability.
PU 3672 A + B odourless PU system with high level of dimensional stability easily pigmented. 5 10 kg 20-40 Shore D 75-80 Low viscosity for detail. Pattern and modelmaking.
PU 368 A + B Two component, odourless polyurethane system to which specific dry fillers can be added. The high flexural strength of this product ensures that parts with thin sections are very strong and not brittle. Extremely high Tg ensures thermal stability at high temperature. Very low and time stable shrinkage. 3 – 4 10 Kg 300 Shore D

76 – 80

Foundry patterns, master patterns, copy models, negatives and fast reproduction models. Especially good in thin sections.
PU 369 A + B Two component, odourless polyurethane system to which specific dry fillers can be added in either the suggested or variable ratio depending on the application. Large volumes of material can be cast in one go. (up to 10kgs) Long pot life. 15 10 Kg or
50 Kg
