## Overview

The ESI Pen with 3M Primer 94 is a professional-grade adhesion promoter designed to dramatically increase the bond strength of acrylic and rubber-based tapes. Featuring a reversible valve-action applicator with two tip widths, it offers precise, mess-free application. This 0.47 fl oz pen dries in approximately 30 seconds and is ideal for automotive and industrial use on low to medium surface energy plastics. Its compact, reusable design ensures efficiency and longevity, making it an essential tool for managers and technicians demanding reliable, high-performance tape adhesion.

## Description

Convenient and easy to use valve action reversible tip. Dispenses 3M Primer 94 in widths of either 0.100"/2.54mm (round tip) or 0.200"/5.08mm (chisel tip). Marker is also available with 3M 4298 adhesion promoter detectable by UV light (search ASIN: B0953S3F5F). Helps increase the bond strength of acrylic and rubber based tapes. Especially helpful on Low Surface Energy (LSE) and Medium Surface Energy (MSE) substrates including common plastics used for automotive dash and interior trim applications (TPO, PPO, PP, PC, PC + ABS, etc). This product can expose you to chemicals which is [are] known to the State of California to cause cancer and birth defects or other reproductive harm.

Review: Used to prep glass for plastic hooks in a display cabinet. Essential to vetting a firm bond. Worked vreat in convenient pen applicator.
Review: As far as I am concerned this is manditory for installing anything with the 3M adhesive tape. MASSIVELY increases the holding strength, but makes it harder to install. The reversable tip is nice, just make sure it is snug as it can pop out if it is not and your product will spill. You will get a ton of uses out of this pen, WAY more than the bags of the single use applicators.

I was searching for 3M Adhesion Promoter wipes and found they were pretty pricey. Came across this pen as a suggested item and thought why not give it a try. It works folks. I use it for helping 3M double sided tape to stick to automotive glass that is in the sun all summer.... use it for automotive accessories. It even helps with command hooks on tough to stick to exterior surfaces.
