First, the scope of application
1. This product is applicable to the anchoring of steel bars, mechanical equipment, and the anchoring and anchoring of buildings, such as various signs and billboards, on concrete, buildings, and road construction.
2. This product is also suitable for the reinforcement and bonding of building structures. The reinforcing steel plates, profiles or other reinforcing materials are firmly bonded to the components of various reinforced concrete structures, such as beams, columns, joints, and brackets. Plates, tunnels, arched roofs, etc. are used to reinforce the load bearing.
3, does not apply to elastic or soft shell products bonding and fixing.
Second, appearance and physical properties
102A-9 Viscosity 25°C2500±150cps, pale white viscous body, shelf life 25°C, 12 months; 102B-9 viscosity 25°C 8100±200cps, light yellow viscous body, shelf life 25°C, 12 month.
Third, the use of methods
Mixing ratio: A: B = 100:50 (weight ratio), usable time: 25°C × 30 minutes (100g mixing amount), curing conditions: 25°C/4-6 hours basic curing (100g mixing amount), 72 hours The best strength is achieved; the surface of the adhered object is cleaned to remove impurities, loose materials, oil, etc. Before use, A and B should be pre-mixed separately; according to the ratio, A and B should be mixed thoroughly after mixing to avoid incomplete curing; after mixing, promptly inject the glue, and try to use it within the usable time. Use the mixed glue.
Fourth, the characteristics of curing
Hardness 85 Shore D, water absorption 25°C <0.15% for 24 hours, compressive strength 70 kg/mm2, shear strength (steel/steel) 18 kg/mm2, tensile strength (steel/steel) 30 kg/mm2, dielectric constant 3.8 to 4.21 KHZ, volume resistance 25 °C 1.35 × 1015Ohm-cm, surface resistance 25 °C 1.2 × 1014Ohm, withstand voltage 25 °C 16 ~ 18Kv/mm.
V. Precautions
1, this product will gradually solidify after mixing, its viscosity will gradually increase, and will release some of the heat;
2. The more glue that is mixed together, the faster the reaction will be, the faster the curing speed will be, and it may be accompanied by a large amount of heat release. Please pay attention to controlling the amount of rubber once dispensed because it can be used due to the quicker reaction. The time will also be shortened, and the mixed glue will be used as soon as possible;
3, the use of time: refers to the conditions at 25 °C, 100g mixed glue viscosity doubled the time, not after the operation time, the glue can not be used;
4, there are a very small number of people exposed to glue for a long time will have mild skin allergies, mild itching, it is recommended to wear protective gloves, stick to the skin, please wipe with acetone or alcohol, and use detergent to clean;
5, before a large number of use, please try a small amount of use, master the use of the product to avoid mistakes.
