Building special two-component polyurethane structural adhesive

Building special two-component polyurethane structural adhesive 1, Product Name: two-component polyurethane structural adhesive special building 2. Picture: 3 Features: two-component polyurethane construction adhesive is applied to the special structure bonding metal, wood, stone, high bond strength plastics and a variety of occasions, foam materials, as structural adhesive use. Technical data (23 ℃, relative humidity of 50%) the main agent component adjuvants Appearance white purple Density (g / cm3) 1.5 ± 0.05 1.2 ± 0.05 viscosity viscous liquid ratio (weight ratio) A / B = 5: 1 operation Time (120 g, min) 60 refer to the amount (g / m2) 800 ~ 1000 initial intensity (hours) 4 hours of high intensity (days) 5 shear strength greater than 15MPa temperature of -40 ~ 80 ℃ instantaneous temperature ( 150 ℃) 40min water weathering long 4 product categories: polyurethane-based glue, two-component, room temperature curing. 5. Size: Main agent 25KG / barrel, adjuvants 5kg / group, co 30kg / group. 6, the main advantages: environmental protection, no significant change in volume before and after curing, rapid curing, superior bond strength, simple construction. 7, the construction process: 1, the adhesion surface is clean and dry surface treatment; 2, according to the ratio and the actual amount were weighed A, B groups were mixed, with not more than, stir in the finished painting the life in order to avoid waste; 3, using a toothed scraping, scratch in construction were prepared on the base; 4, in the adhesive in a relatively liquid, began construction, to ensure full access to the adhesive bonding surface; 5, the construction 24 require auxiliary fixing jig or formwork which may be removed when the glue reaches the initial strength within hours. 8, the product shelf life and precautions: 1, the adhesive should be stored in a cool, dry place, in unopened cases save up to nine months; 2, adhesives, non-toxic, but should avoid swallowing and eye contact, in the event of an accident, please immediately see a doctor.
