MAX BOND THIXOTROPIC is paste like in consistency but maintains the adhesion performance of MAX BOND Medium Viscosity. It is specially formulated so that the adhesive will not flow allowing the user precise and clean adhesive placement.
This money-saving 64-ounce kit (combined volume of 1/2 gallon) is a handy item for hobbyists, marine and aircraft repair and construction.
STORE IN A COOL DRY PLACE AND IT CAN LAST UP TO SEVERAL YEARS
REPLACE THE LIDS SECURELY OF THE CURING AGENT AS IT WILL
ABSORB AMBIENT MOISTURE AND AFFECT THE SHELF LIFE
MAX BOND THIXOTROPIC is a general purpose high strength adhesive is used in all types of bonding application where excellent water resistance and a wide service temperature exposure is expected. This resin system is an industry “work horse” standard and is the most versatile system available. It can also be used as a reinforcing resin for Fiberglass, Aramid( Kevlar Type) Fibers, Carbon Fiber or as crack filling resin and surface sealing for many different types of substrates.
Used in hundreds of applications
Marine and Aircraft repair
Fiberglass To Fiberglass Bonding
Golf Club Assembly
Concrete bonding, patching, sealing
Electronic Potting, Insulating, Encapsulating
Woodwork bonding, caulking
Composite Adhesive, Laminating
Honeycomb Bonding and Edge Closeout
MAX BOND THIXOTROPIC does not contain nonreactive plasticizer that typically deteriorates the cured property over time. It is approve for direct and indirect food contact applications.
Measure equal amounts of Part A and Part B, mix and apply and allow to cure overnight. It has a 90 minute working time and can be handled in 6 hours. A strong bond will develop in 10 hours of room temperature curing and will fully cure within 24 to 36 hours. Heat curing is also ideal for MAX BOND for a faster cure time and will maintain its non-flowing properties at elevated temperatures. The mixed consistency is similar to peanut butter and is easily applied using a brush, spatula, trowel or injected into place using a syringe.

Surface Treatment Prior To Bonding
In virtually every application the quality of the bond between the resin system and the surface to which it is applied is improved if the surface is clean and dry.
This is particularly true of adhesive applications where stress will be applied to the cured bond line.
It is also true where protective coatings are used. The following surface preparation procedures are recommended.
Degrease – Wipe laying surfaces with Methyl Ethyl Ketone (MEK) or acetone to remove all oil, dirt, and grease.
Etch – For optimum results, metal parts should be immersed in a chromic acid bath solution consisting of:
- Sodium dichromate – 4 parts by weight
- Sulfuric acid – 10 parts by weight
- Water – 30 parts by weight
The solution should be held at a temperature of 160°F (71°C), and the parts left immersed for 5 to 7 minutes.
Rinse – remove metal parts from etching bath and rinse in clean cold water (de-ionized water is recommended). If thoroughly clean, metal surfaces so treated will hold a thin film of water.
Dry – To accelerate drying, items to be bonded can be placed in an air-circulating oven.
Degrease, scour and dry – Often etching as outlined above is not practical. The metal surfaces may be cleaned by degreasing as noted above, scouring with an alkaline cleanser followed by rinsing and drying.
Degrease and dry – Degrease the surface as noted above, sand or sandblast the surface lightly but thoroughly. Rinse with acetone or Methyl Ethyl Ketone (MEK), and dry.
Degrease – With MEK as above, or with a strong boiling solution of a good grade household detergent.
Etch – For optimum results, degreasing can be followed with the chromic acid bath outlined above.
Sand – Bonding surfaces should be sanded lightly, but thoroughly to remove all external contamination.
Clean – Carefully remove all dust, or particles of wood from sanded areas. A stiff and clean brush, or compressed air can be used.
Clean – Remove all dirt, oil, or other surfaces contaminate with detergent sop or degreasing solvent and water, followed by thorough rinsing and drying. A solvent that does not have a detrimental effect may also be used.
Sand – Surfaces to be bonded should be sanded lightly, but thoroughly to remove surface sheen.
Clean – Carefully remove all dust or particles of plastic from the sanded area. A clean brush, lint free cloth, or compressed air may be used.
Epoxy Resin have a definite working time (pot life), after mixing the components together.
The Working Time is greatly affected by the amount of resin that is being mixed per batch. Other factors such as the ambient temperature of the environment and the temperature of the PART A and PART B respectively will also affect the rate of cure.
There are two aspects that must understood when working with epoxy resins once the curing agent and epoxy are combined:
Working Time: Relates to the time that the adhesive will provide the best performance when it is applied unto the substrate. As the epoxy begins to polymerize, energy is typically released and its evidence can be observed as heat generation, called exothermic heat. Since heat can affect the viscosity and length of time that the adhesive convents for a liquid to a solid, spreading the adhesive in to a film will prevent the heat energy from concentrating in the container and cause auto-acceleration. To yield the full strength that was engineered into the epoxy resin, it important that the mixed resin be applied within the established working time. An exponential decrease in mechanical properties and adhesion quality will be experienced the longer the mixed resin is left in a confined mass.
Thin Film Set Time is the time duration which denotes the amount of time the resin will convert from a liquid to a solid. This time difference is typical 4 to 6 time longer than the working time. The generated exothermic heat energy is diffused into the ambient environment thus prevent it from generating the any excessive heat energy that will auto accelerate the working time.
