One Component, High Temperature Resistant Epoxy Offers a Low Coefficient of Thermal Expansion

Featuring a low coefficient of thermal expansion (CTE) of 15-20 x 10-6 in/in/°C, Master Bond EP13LTE is a one part epoxy for structural bonding applications. “EP13LTE is very convenient to use, since it doesn’t require mixing, and has an unlimited working life at room temperature,” said Venkat Nandivada, manager of technical support. “Besides being easy to handle, this system also offers superior resistance to high temperatures, with a glass transition temperature of approximately 160°C.”

EP13LTE cures readily in 1-2 hours at 300-350°F. This epoxy paste has limited flow while curing. It bonds well to many substrates such as metals, glass, composites, ceramics and plastics. Once cured, EP13LTE has an impressive strength profile delivering a tensile lap shear strength of 2,600-2,800 psi, a compressive strength of 24,000-26,000 psi and a tensile modulus of 500,000-550,000 psi. This dimensionally stable system is able to withstand 1,000 hours at 85°C/85% RH and maintain a Shore D hardness of 90.

With a volume resistivity exceeding 1015 ohm-cm, EP13LTE has reliable electrical insulation properties. This system also passes ASTM E595 testing for NASA low outgassing. It is serviceable over the wide temperature range of -60°F to +500°F [-51°C to +260°C]. This tan colored system is available for use in syringes, jars, ½ pints and pint containers.

Adhering to Painted Metals

Most adhesives should be able to bond to a painted surface. However, if longevity is of concern, the removal of the paint is often recommended, since the bond strength to the bare metal of an epoxy adhesive for example, could be as much as 2-3 times the bond strength achieved on a painted metal surface. Please see table below:

High Temperature Resistant, NASA Low Outgassing Approved Epoxy for Die Attach Applications

Formulated for die attach applications, Master Bond EP17HTDA-1 is a one component epoxy that can also be used for bonding and sealing. “EP17HTDA-1 has the ideal viscosity and flow for die attach applications,” said Rohit Ramnath, senior product engineer. “It has a high glass transition temperature (Tg) and also offers excellent electrical insulation properties, even at elevated temperatures and low exotherm upon curing.” This system features an excellent die shear strength of 24-27 kg-f and can be used in a typical die size ranging from 4-400 mm2.

EP17HTDA-1 has exceptional temperature resistance with a service temperature range of -80°F to +600°F [-62°C to +316°C] and a Tg of 195-205°C. This compound boasts thermal conductivity of 9-10 BTU•in/ft2•hr•°F [1.30-1.44 W/(m·K)]. It withstands a variety of chemicals including acids, bases, salts, fuels, oils and many solvents.

As a one part system, EP17HTDA-1 does not require any mixing for use and is curable in the temperature range of 300-350°F in short durations. It bonds well to a wide variety of substrates, such as metals, ceramics, plastics and composites. Upon curing, it delivers a tensile lap shear strength of 2,400-2,600 psi and a tensile strength of 9,000-10,000 psi. It also has minimal shrinkage upon curing.

While EP17HTDA-1 is well suited for electronic and related applications, it can also be used in vacuum situations as it passes NASA low outgassing testing. This epoxy is available for use in 10 cc and 30 cc syringes and has a shelf life of 3-6 months when stored at 40-50°F.

Precise Alignment Stability

Multiple Master Bond adhesive systems were developed to ensure exact alignment retention in structural bonding applications. The need for these formulations has grown significantly as thinner, lighter, durable, miniaturized electronic/optical devices require precise tolerances for adhering similar/dissimilar substrates subjected to fluctuations in temperatures, stresses, moisture,

Adhesive Bonding for Improved Aesthetics

Visual aesthetic design plays an important role in new product development. It is imperative to product differentiation, branding and marketplace sales. Unique appearance requires collaboration/coordination with suppliers who bring external expertise.

One Component Elastomeric Primer/Adhesive System Meets ISO 10993-5 Specifications

Developed for priming and bonding polyolefinic substrates, Master Bond X21Med is a single component elastomeric compound that passes ISO 10993-5 tests for cytotoxicity. “This specialty system was designed to be used as a primer that would promote adhesion between polyolefins and other surfaces such as metals, ceramics, composites and other kinds of plastics. Surfaces primed with X21Med are compatible with a wide variety of adhesives,” said Venkat Nandivada, manager of technical support. “It can also be used to bond two polyolefin materials.”

X21Med is easy to use, either as an adhesive or a primer. It has a low viscosity of less than 250 cps and cures at ambient temperatures or more rapidly with heat. As a primer, it is simply applied in a thin layer to the surface and the solvent is allowed to evaporate. When used as an adhesive, X21Med should be applied to both substrates and then mated. The maximum area of bonding effectiveness is about 1 square inch. Once cured, this clear to light amber colored product is tough and not rigid. It is a reliable electrical insulator and has a volume resistivity exceeding 1014 ohm-cm. X21Med is serviceable from -60°F to +200°F [-51°C to +93°C].

Since polyoelefin plastics are used in almost every industry, X21Med is well suited for use in medical device, aerospace, electronic and specialty OEM applications, among others. This system is available for use in pints, quarts, gallons and 5 gallon containers.
