polycarbonate board adhesive

Specifications

PC board adhesive

Adhesive PC board use PC special glue.It's firmly,beautiful,no print left.It's applible to all kinds of box,machinery accessories parts,handicrafts.

characteristics:

Impact resistance: The impact of PC board up to 3kg/cm. The impact strength of PC board is 250-300 times as common glass, is 20-30 times as acrylic sheets, is 2 times as toughened glass. And almost it’s no fracture risk. Falling the hammer with 3kg and two meters above it, that’s no crack. So it enjoyed the reputation of being of "safety glass" and "ring steel".

light transmittance: daylighting is admirable, light transmittance rate up to 85 ~ 91%, and its transparency can be comparable with glass. In sunlight it won’t product yellowing, fogging or less light transmittance. UV coated board loss light rate is only 6%, but PVC is as high as 15% - 20% and glass fiber 12% - 20% ten years later.

Weatherability: The surface is with anti-ultraviolet co-extrude layer, which can prevent ultraviolet sunlight caused resin aged and turn yellow. Surface co-extrude layer has chemical bond can absorb ultraviolet radiation and translated it into visible light, which effect plant photosynthesis stabilization. It doesn’t fade in outdoor for ten years. In - 40 °C at 130 °C scope to keep all the physical index stability. 4000 hours aging test of climate, yellowing degree is only 2, lower light transmittance value only 0.6 percent.

Resistance to flammability: PC board itself is not spontaneous combustion and have automatic quench. It accord with European Union ROHS instruction and strict UL safety standard, and UL94 fire prevention grade up to levelV0, levelV2, level HB. PC board itself is lighted 580°C. Remove from the fire source, it will be self-extinguish. It won't produce toxic gases, nor foster the fire spread when it’s burning.

Resistance to Heat, resistance to cold: During the temperature from - 40 °C to + 130 °C, it will not cause deformation or degrade the quality. PC board will not be ductile-brittle in - 100 °C, nor be softened in 137.3°C. Its mechanics and mechanical properties have not obvious changes in hostile environments.

Light rigid: It’s light. It’s as only half weight as the glass, as1/3 weight as acrylic board. Owing to good adaptability and safety, it’s easy to handle, drilling. When installed, it’s not break, simple construction and easy to process.

High plasticity: On site, it can be cold bending formed, install arched and hemicycle top or Windows depends on drawings. Minimal bending radius is 170 times thickness of used board and it can be hot bending formed.

Sound insulation: The effect of PC board sound insulation is obvious, it’s more effective sound insulation than glass board and acrylic board with the same thickness. In the same conditions, the sound insulation quantity of PC board is 3-4DB larger than glass. It is first choice material to be used in highway noise barriers in the world.

Energy Saving: It keeps building cool in summer, and it keeps them warm in winter. The thermal conductivity (K value) of PC board is less than common glass and other plastics. The effect of heat insulation is 7%-25% higher than glass with equal level. The rate of heat insulation is highest to 49%. Thus it can reduce heat loss greatly, suit for buildings with warm equipments, belongs to environmental protection material.

Prevent dewing: When outdoor temperature is 0°C and indoor temperature is 23 °C and indoor relative humidity is under 80%, the inside surface will not dew.
