Description：
Wellmid 2013 is a multi-purpose, two-component, room temperature cured semi-flow viscosity epoxy adhesive, long working time, high strength and toughness. Suitable for bonding metal, ceramic, glass, concrete, wood, some rubber, hard composite materials and plastics, and most common materials. Main applications include the bonding and repair of jewelry and handicrafts, the production and assembly of electronic components and industrial parts, and the bonding construction of large areas.
Key properties：
● Longer working time
● Low shrinkage, high strength, good toughness
● Semi-flowing liquid
● Can be bonded to most materials
● It has good dynamic load performance
● Mix ratio by volume：100:100 / Mix ratio by weight：100:80

● After 2013 AB cured, the color is light yellow and transparent, and black, gray, brown, and silver gray are also produced. For details, please refer to the product drawing;
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 2013 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：
| Curing temperature | 5℃ | 15℃ | 25℃ | 40℃ | 60℃ | 80℃ | 100℃ |
| Cure time to reach 50% shear strength | 24H | 15H | 7H | 3H | 45min | 30min | 10min |
| Cure time to reach 100% shear strength | 168H | 72H | 24H | 5H | 90min | 50min | 20min |
●More 2013 A and B is mixed at room temperature, the faster the curing will be, the shorter the working time will be, and the glue will become more yellow due to excessive heat duri ng the curing reaction;
● DIY workers mixing the glues on the plastic lid that comes with th e tin can reduce pollution. And the glue remaining on the plastic lid can be easily removed after the glue has cured;
● Side-by-side cartridges and the static mixer is suitable for continuous production of the dispensing gun / machine, which can greatly improve production efficiency and reduce waste and pollution.
Storage and Packing：
Wellmid 2013 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.
Package: 2oz(56.7Grams) / 1.8lb(817.2Grams) / 1.8kg Tin can sets; 25Grams / 50ml / 600ml Cartridge.
