Understanding Tack vs. Cure

When looking at the bond strength of adhesives, it is important to differentiate the strength of the

bond when the substrates are initially bonded from the strength of the bond after the adhesive has

cured. This document is designed to address the initial bond strength. As we compare the initial

bond strength of SIMALFA vs. a solvent based adhesive, it is important to understand tack vs. cure.

SIMALFA will tack instantly, while a solvent based adhesive will cure instantly. We fi nd that the

instant tack offered by SIMALFA allows for much more versatility and speed in your production and

processes when compared to the instant cure of a solvent based adhesive.

The best way to demonstrate the difference is to look at the simple tack tests illustrated on page 2

of this document: shear strength, pull strength, and peel strength.

Shear Strength

When we refer to shear strength, we refer to the strength of the adhesive bond while attempting to

slide 2 parallel bonded substrates past each other. Both SIMALFA and solvent based adhesives offer

instant shear strength.

Pull Strength

Pull strength refers to the strength of the bond when pulling the substrates in a direction that is

perpendicular to the bonded surface. Both SIMALFA and solvent based adhesives offer instant

pull strength.

Peel Strength

Peel strength is determined by the ability of the adhesive to resist separation when a substrate is

peeled up from the edge to remove it from the material to which it has been bonded. This is where

we fi nd the key difference between SIMALFA and solvent based adhesives. SIMALFA is designed to

allow the substrates to be peeled and repositioned while the adhesive is still wet. This will allow the

operators to correctly position and reposition the substrates without damaging them, or having to

apply more adhesive. This provides numerous advantages that can help with speed, process, and

overall quality. Solvent based adhesives do not allow for this. It is again important to note that once

SIMALFA has cured, peeling will result in destruction of the substrates.

La comprensión de Fijar vs. Curar

Al mirando la resistencia de la adherencia de los adhesivos, es importante que distingue la resistencia de

la adherencia cuando los sustratos se adhieren inicialmente de la resistencia de la adherencia después de

el adhesivo ha curado. Este documento está diseñado para tratar la resistencia inicial de la adherencia.

Mientras comparamos la resistencia inicial de la adherencia de Simalfa vs. otro adhesivo basado en

solvente, la comprensión de fi jar vs. curar es importante. Simalfa fi jará inmediatamente, pero un

adhesivo basado en solvente curará inmediatamente. Encontramos que la fi jación inmediatamente que

SIMALFA ofrece permite más versatilidad y velocidad en su fabricación y sus procesos comparado con la

curación inmediatamente del adhesivo basado en solvente.

La manera mejor para demonstrar la diferencia es mirar a las pruebas simples de la fi jación que están

ilustrados en página 2 de este documento: La resistencia a cortar, la resistencia a tirar, y la resistencia a

pelar.

La resistencia a cortar

La resistencia a cortar se refi era a la resistencia de la adherencia del adhesivo cuando trata de mover los

dos sustratos paralelos que están adheridos en dirección contraria uno al otro. Ambos productos, SIMALFA

y los adhesivos basados en solvente, ofrecen la resistencia inmediatamente a cortar.

La resistencia a tirar

La resistencia a tirar se refi era a la resistencia de la adherencia cuando tira los sustratos en una dirección

que es perpendicular a la superfi cie adherida. Ambos productos, SIMALFA y los adhesivos basados en

solvente, ofrecen la resistencia inmediatamente a tirar.

La resistencia a pelar

La habilidad del adhesivo resistir la separación cuando un sustrato está pelado del borde para sacarlo

de la materia a que ha sido adherido determina la resistencia a pelar. Aquí encontramos la diferencia

esencial entre SIMALFA y los adhesivos basados en solvente. SIMALFA es diseñado para permitir el pelar

y el recolocar de los sustratos cuando el adhesivo todavía está limpia. Este permite que los operadores

puedan colocar correctamente y recolocar los sustratos sin dañarlos o sin la necesidad de aplicar más

adhesivo. Este proporciona muchas ventajas que pueden ayudar con la velocidad, el proceso, y la

cualidad total. Los adhesivos basados en solvente no permite esto. Es importante otra vez para apuntar

que cuando SIMALFA ha curado, el pelar resultará en la destrucción de los sustratos.
