Magnobond 6504 and 6507, Parts A & B

DESCRIPTION

Magnobond 6504 (liquid) and 6507 (thixotropic paste) are two component epoxy compounds formulated to seal electrical wire in saw cuts and embed light fixtures in concrete and asphalt airport runways. The systems are formulated to be flexible with sufficient elongation to relax any stresses due to thermal and mechanical changes. The liquid system (6504) is designed to allow the use of dry sand and provide a thermal expansion characteristics similar to concrete. Sand, of course, will make the system fill more voids by increasing the volume by two-thirds.

NOTE: SOME SANDS DO NOT WORK WELL

SPECIAL FEATURES

Compounds 6504 and 6507 can be used in either concrete or asphalt runways.

Compound 6504, A & B, is a low viscosity liquid compound designed to cure as low as 45°F, making the material a versatile product for use in cool weather.

Compound 6507, A & B, is a modified version of 6504, incorporating a thickening or thixotropic agent to produce a smooth paste suitable for application by trowel or spatula. 6507 will also cure at temperatures as low as 45°F.

MIXING

Thoroughly blend equal volumes of Part A and Part B until homogeneous. 6504 and 6507 cure faster in large masses than in thin films. Pot life will also be shorter in large masses. 6504 and 6507 should be mixed at room temperature or below in quantities which can be used immediately. See Magnolia Technical Bulletin - Mixing, Storage and Handling of Epoxies.

APPLICABLE SPECIFICATIONS

These products were formulated to meet or exceed FAA Material Specification Item P-606, Amendment #1, dated February 17, 1989 - Adhesive Compounds, Two Component, For Sealing Wire and Lights in Pavement.
