Liquid Photopolymer

Description

Stampera flexible photopolymers are essentially Methacryl-Urethane Photosensitive resin. The resins polymerise when exposed to ultra violet source of light energy. The polymerisation process occurring in plate making equipment converts liquid resin into elastomer plate. These plates are used for making rubber stamps and making polymer plate for printing on corrugated box, label, envelope etc.

Advantages of Stampera Resins

• Photosensitive polyurethane elastomer with coloured viscous liquid form
• Polymerizes when exposed to ultraviolet (UV-A) light with spectrum range between 315 and 380 nanometers
• Water washable – no need for organic solvents during the process
• Non-toxic, non corrosive, non harmful monomers
• Environmentally friendly

Properties of Finished Plates and Rubber Stamps

• Excellent printing quality
• Good dimensional stability, tack free plate
• Long life if not exposed to direct sunlight
• Long working life, long press life
• Easy mounting on printing presses
• Compatibility with both water reduced inks and oil based inks
• Extremely economic plate price

Safety Information

• All Stampera resins have an LD50 exceeding 5000 mg/kg of body weight (non-dangerous products)
• When producing stamps wear protecting clothing, gloves and UV resistant safety glasses
• Do not expose the liquid photopolymer to direct sunlight
• Store at temperature between 2° and 28°C in closed container
