Crystal Cast 400 is a two component polyurethane system which is water clear when cured. Crystal Cast 400 is ideal for casting in bulk such as sculptures, embedding decorative objects and other similar applications.
High Strength Flexible PU Matrix
High Strength Flexible PU Matrix for PU3543, PU3544, PU3545, PU3546, PU3547, PU3548, PU3551, PU3549 and PU3550. These are tough, durable, polyurethane elastomers varying from 30-95 Shore A, used for mould making or prototype parts requiring high tear strength and excellent abrasion resistance. Please see Tech Data for Matrix.
PU 342
PU 342 is a flexible polyurethane system of 55-60 shore A, used for mould making or prototype parts requiring semi rigidity.
PU 3426
ALCHEMIX PU 3426 is a tough flexible polyurethane system of 57 - 63 Shore A, designed specifically for offshore applications requiring good tensile strength and chemical resistance. The system exhibits a rapid development of properties while retaining a relatively long useable life.
PU 343
ALCHEMIX PU 343 is a semi flexible polyurethane system of 87 – 92 Shore A, used for mould making or prototype parts requiring semi rigidity.  
PU 3434F
ALCHEMIX PU 3434F is a tough flexible polyurethane system of 78 – 83 Shore A, designed specifically for offshore applications requiring good tensile strength and chemical resistance. The system has a fast cure and exhibits a rapid development of properties.  
PU 3435
ALCHEMIX PU 3435 is a tough elastomeric polyurethane system designed specifically for offshore uses requiring high tensile strength and chemical resistance. The system exhibits rapid development of properties while retaining a relatively long usable life
