2015 Two Component Caulking and Super Strength Epoxy Adhesive

Description：

Wellmid 2015 is a two-component epoxy super strength structural adhesive developed specifically for the bonding as aluminum, iron, copper, stainless steel and other metals and thermosetting plastics such as GRP and CFRP. No solvent, no smell, with high caulking and thixotropic, very long working time, working temperature is -60~120°C, fatigue resistance, chemical and water and weather resistance excellent performance. Widely suitable for mechanical equipment and pipeline assembly production and outdoor heavy industry bonding and repair.

Key properties：

● Suitable for structural bonding under high dynamic load

● Non-flowing thixotropic caulking adhesive, the filling reach 40mm

● Very long working time, easy to large area construction

● Can be bonded to most materials, especially glass fiber reinforc ed plasticsl and metal

● Excellent weather, water and chemical resistance

● Mix ratio by volume：100:41~45 / Mix ratio by weight：100:44~50

Pretreatment：

The strength and durability of a bonded joint are dependant on proper treatment of the surfaces to be bonded. At the very least, joint surfaces should be cleaned with a good degreasing agent such as acetone, alcohol or other proprietary degreasing agents in order to remove all traces of oil, grease and dirt. The strongest and most durable joints are obtained by either mechanically abrading or chemically etching (“pickling”) the degreased surfaces. Abrading should be followed by a second degreasing treatment.

Application of adhesive：

Wellmid 2015 AB must be thoroughly mixed in the corresponding proportion to achieve the best bonding effect.

Side-by-side cartridges and the static mixer can achieve better mixing results while increasing efficiency and reducing waste and pollution. The resin and hardener can be applied directly to the pretreated dry bonded surface through the mixer. A layer of 0.05-0.10mm thick adhesive layer can completely wet the adhesive surface, and give the adhesive with maximum shear strength. Too thick adhesive layer and too much glue around, and can not bring greater bonding strength to the adhesion.

Equipment maintenance：

All tools should be cleaned with hot water and soap before adhesives residues have had time to cure. The removal of cured residues is a difficult and time-consuming operation. If solvents such as acetone are used for cleaning, operatives should take the appropriate precautions and, in addition, avoid skin and eye contact. Used cartridges and mixers cannot be used again.

Curing Time and Temperature：

Wellmid2015 can achieve a basic curing state at room temperature with excellent strength, but due to the formulation's design of a medium to high temperature post-curing activation program, the program can significantly improve bond strength and temperature resistance. It is recommended that after curing at normal temperature for 8-24 hours, the temperature rises to 80° C ~120° C and curing again for 30 minutes ~3 hours.Or refer to the above table to select the curing temperature and curing time suitable for the production process to achieve the best performance of the product formulation design.

DIY workers mixing the glues on the plastic lid that comes with the tin can reduce pollution, and the glue

remaining on the plastic lid can be easily removed after the gl ue has cured;

Storage and Packing：

Wellmid 2015 A and B must be stored at room temperature provided the components are stored in sealed containers. Avoid sunlight, the longest effective time of the product can be more than 36 months; The expiry date is indicated on the label.
