PUR 33 - The Universal Casting Resin for Reliable Insulation and Protection 

The PUR 33 was specifically developed for the electrical insulation and mechanical protection of cable connections in the low voltage range. It can also be used for medium voltage cables to provide effective moisture and mechanical protection. Thanks to its composition and packaging, it is ideally suited for both indoor and outdoor use.

Processing is particularly safe and convenient: The resin is delivered in a transparent two-chamber bag and indicates through a patented color change from blue to green when the mixture is homogeneous and ready for use. The cold-curing, hydrophobic resin has excellent flow properties, low volume shrinkage, and reliably adheres to all common plastic cable types.

Main features:

• Developed for low voltage cable connections, also suitable for medium voltage cables
• Indoor and outdoor application 
• Delivered in a practical 2-chamber bag with color change (blue → green)  for mixing control 
• SFSystem: clean hydrophobic, can be processed even under water influence 
• High hydrolysis resistance, UV, weather, and aging resistant 
• Good curing even at low temperatures 
• Excellent impact resistance and resistance to atmospheric corrosion 
• Excellent adhesion on PVC, PE, PP, VPE (e.g., NYM, N(A)YY, NYCWY)
• SVHC-free no hazardous ingredients - cured residues can be disposed of in household waste

Conclusion: PUR 33 is the universal solution for permanent, safe, and uncomplicated casting work - even under the most challenging environmental conditions.
